E!'s Chelsea Handler doesn't just hand out invitations to her show to anyone. You have to romance her a little first.

So when David Hasselhoff requested that he come on the show to promote his upcoming movie The Christmas Consultant, Chelsea drew up a very specific list of requests (read: demands).

The result: a wildly extravagant musical number, the likes of which the Chelsea Lately stage has never seen, or at least not seen in the past week. There were props, there was dancing from the Chelsea Lately Backup Dancers (who have clearly learned a lot since Fergie's appearance), and of course there were the musical stylings of The Hoff, who wished everyone a happy and "Hoffy" holiday.

But the coup de grace was the move that The Hoff pulled on Chelsea at the end of the number, leaving Chelsea "obviously gobsmacked." What did he do? Tune in to Chelsea Lately tonight at 11/10c to find out!
